Got a remote start installed last month that uses the factory key fob. Installation is an easy DIY. So far it has worked pretty good. Push lock 3 times to start and it does. I had a long range extender added and bought just a transponder key so I don't have to carry around the OEM key anymore. Just need to program the key that I just had cut yesterday. Scroll down on this site to see/order kit. Been told will work on most Chrysler products.
